This guy’s guide is really, really good. Screenshots and all!

My goal with this guide is to make it as easy as possible for everyone to install a 3D desktop on Ubuntu Linux (Edgy Eft) with Beryl and Xgl, there will be no use of the terminal in this guide so everyone should be able to follow this guide and install a 3D Desktop on there very own and brand new installation of Ubuntu Edgy Eft.[ From ]
